Decompiled Shadow Hearts: Covenant (PS2) and implemented a native Rust/Bevy port

The project documents a partial decompilation of the PlayStation 2 title Shadow Hearts: Covenant (SH2) and a native reimplementation using the Rust programming language and the Bevy engine. The author reports that the Japanese demo executable (SLPM_602.19) contains a full symbol table, which serves as the primary source for class layouts, names, and the call graph. These symbols are applied to the stripped US retail build (SLUS_210.41), which is the target for the port. The repository contains no game data, requiring users to provide their own ISO images or extracted folders. Development involves a workflow where Ghidra output is cleaned and mapped to Rust modules, including sh2_core, sh2_gfx, and sh2_battle. The author credits Claude Opus 5, Claude Sonnet 5, and Claude Opus 5.5 as co-authors for various commits, including the development of battle, field, and UI modules. The port status is tracked via a ledger, covering approximately 43% of game functions. The author notes that attempts to use the Taikenban demo symbol table to recover names for the US retail build were unsuccessful, citing significant design changes between the demo and retail versions.
